Recurrent ischemic stroke due to damage to the middle cerebral artery causes deterioration of neurological function and increases the rate of disability, death, and treatment costs many times compared to the first ischemic stroke. Assessing risk factors plays an extremely important role in preventing recurrent ischemic stroke. We have discuss some risk factors for recurrent ischemic stroke caused by middle cerebral artery damage.
